PIPE-UNION.

Application filed May 3, 1900. Serial No. 15 ,404. (No model.)

To all whom, t 11m/,y con/cern:

Be it known that we, BENJAMIN VERG, builder,of Paris, and EMILE DAGAIN, builder, of Narbonne, inthe French Republic, havein- Vented a certain new and useful Pipe-Union,

of which the following is a full, clear, and eX- act description.

This invention relates to a union -or connection for, in general, quickly effecting the It is particularly applicable to the connection with the Valves of pneumatic tires of the pump for infiating the said tires.

Upon the accompanying drawings two forms of application of our invention are illustrated by way of e'xample.

Figure l shows in longitudinal section a union or connection more particularly constructed for pipes of large size, such as wazo ter-pipes, hose-pipes, and the like. Fig. 2 is a cross-section on line 2 2 of Fig. 1. Fig. 3 is a longitudinal section of an improved connection applied to the Valve of a tire and to a pump for iniiating the same. Fig. 4 shows z 5 in elevation the connection when in the unclasping position. Fig. 5 is a cross-section on line 5 of Fig. 4.

Ourunion in every case comprises, essentially7 a cylindrical socket a, rendered integral with a metallic tubular portion b by a pin, peg, or the like b or in any other suitable manner. The socket a is provided with several longitudinal slots, formi-ng a certain number of flexible plates or bushes a CLL-four, for example-and are formed with turnedover ends a; oc. Upon this socket d is mounted, frictionally, a ring or sleeve c, which can be slid thereon. We prefer to form the sleeve c with a groove c1", into which the head of the 4o screw b' may protrude to form a stop for the sleeve. Within the socket a is inserted a end of one of them is slipped upon the tubular portion b. The other is passed onto a similar tubular portion g, the inner end g' of which is shaped with an enlarged end and a groove 'y in such manner as to be able to enga-ge the end of the interiorrubber tube d and to slightly distend it. The sliding sleeve c being moved so as to free the flexible parts of the split socket a', the tubular portion g is inserted into the tube d. The latter being distended causes the widening or forcing outwardly of the iiexible plates a', and the sleeve cis then slid so as to bring it over these'latter, and thus to effect a claspin g or contractile action of the said plates. The latter are then brought together and compress the rubber tube d around the end g of the tubular portion, forcing the turned-over portions of the flexible tube into the groove y of the tubular portion g, and this securely connects these two portions and elfects an air-tight joint between them. In order to separate them afterward, we have only to move the sleeve c so as to disengage the flexible plates a', which thereupon cease to clasp the tube d.

When our joint or union is employed to connect a tire-valve with an ordinary pump connection, Figs. 3, 4, and 5, the joint or union itself, as before described, forms part of the tube or connection 71 the tubular portions g' g being then replaced by an ordinary cone gw, which is screwed upon the threaded por# tion t' of the valve fi', and upon this cone g10 the tube d of the joint is adjusted.

We may apply this improved union or coupL ling to purposes other than those referred to, and the union may be modified in shape and also be made of any convenient sizes.

' We claim as our invention@ A pipe-union or the like, comprising a slotL Vted cylindrical socket, having at one end turned-over ends no, and secured at the other end to a pipe, a helloT iiexible tube in the interior of the slotted socket and a sleeve surrounding the outside of the slotted socket and adapted to be slid thereon,- in combination with a second pipe having a terminal with an enlarged end, a grooveybehind said enlarged end, whereby on the insertion of the enlarged end into the slotted socket, and 5 upon the sliding of the sleeve thereon, the turned-over ends of the slotted socket Will positively hold the two pipes against parting longitudinally and at the same time the enlarged end will compress the exible inner lo tube of thecoupling to form a tight joint.

In testimony whereof We have signed our names to this specieation in the presence of the subscribing Witnesses.
